Hey,
I have a 1990 e30 M3 that i swapped a 1999 E36 M3 motor and currently have the stock exhaust manifold. The car pulls like and animal with lots of low end torque and have picked up a set of euro headers. I was told i will lose a lot of the low end pull. Has anyone put a set of these headers on a E36 m3 motor and how did it change the characteristics of the car?
